PETER A.. OSHANYK, 0F WILTON, NORTH DAKOTA.

To all whom it may concern.'

Be it known that I, PETER A. OSHANYK, a citizen of the United States, residing at `iVilton, in the county of McLean and State of North Dakota, have invented certain new and useful Improvements in Timers, ot which the following is a specification.

This invention relates to timers for internal combustion engines, and it comprises a supporting bracket, a lever pivotally mounted thereon, one end of said lever forming a. contact, a cam engaging the end of said lever, a slidable rod engaging said cam, connectingmeans between the said slidable rod and said lever to intermittently separate said Contact and cam, and speed controlled means for rendering the mechanism inoperative.

In the present invention, I have provided a timer for gas engines ot the jump spark type, wherein the parts are of simple construction and are very-unlikely to get out of order. The contact is made between a cam and a pivoted lever, and means are provided, also-operated by the same cam, to swing the pivoted lever at regular intervals and thus separate the contact end of the lever and cam.

I have further provided means for maintaining the contact end of the lever and the cam spaced when the speed of the engine eX- ceeds a predetermined limit. A governor operated by the engine at a speed proportional to the engine speed is connected to the slidable rod and is adapted to actuate said rod and the connecting means of t-he pivoted lever, whereby the contact end of the lever will remain separated from the cam when the speed of the engine exceeds the speed for which the governor is set.

In the accompanying drawings, I have shown one embodiment of the invention. In this showing: v

mounted on a base 2, and provided with a spark plug 3. The plug is energized by the coil 4t which is connected thereto by means of a connection 5, the circuit being grounded on the engine cylinder by connection 6. A source of energy 7 is connected to the coil by connection S, the other terminal of the battery or other source of energy being connected to the timer. The parts heretofore described are of the usual construction and forni no part of the invention except in the combination claimed.

The timer comprises a supporting bracket 10, one end of which is supported on a portion of the engine, as at 11. A depending arm 12 is arranged on the other end of the bracket, and this arm is secured to the supporting member' 13, arranged on any suitable support. As shown, the supporting member 13 forms one of the bearings of the main crank shaft 14. A lever 15 is pivoted to the supporting bracket, as at 16, the end of the lever being secured to an arm 17, slidablv mounted on the depending portion 12 of the supporting bracket. The arm is maintained in position with respect to the bracket, by means of a clip 17 embracing the arm 17, and the depending may be secured to the arm by any suitable means, such as bolt and nut 18. The lower end of the arm is offset, as at 19, and is provided with a contact member 20. The lead wire 9 passes through an insulating tube 21 arranged on the pivoted lever and is; connected to the contact 20. A cam 22 is arranged on a shaft 23 driven from the main crank shaft in any suitable manner, and this cam normally contacts with the contact member 20, the members being maintained in contact by a spring 24, one end of which is secured to bearing 13 and the other end to a hook 25, formed on the end of the slidable arm 16. A slidable member 26 is mounted in suitable guides 27 carried by the engine or engine frame, and this member is provided with a roller 28 which also engages the cam 22. A sleeve 29 surrounds the slidable member and is maintained in adjusted position thereon by a set screw 30. This sleeve is provided with a pair of ears for the reception of one end of a connecting member 31, the other end of which is securedto the pivoted lever, as at 32. The connectingmember is provided with a turn-buckle 33, whereby the length may be varied.

A shaft 34 mounted in bearings 35, is

portion 12. This clip driven from the main crank shaft in any suitable manner. This sha'lt is provided with a governor. connn'ising a pair ot sleeves 36 and 37. The sleeve 36 is ured. to the shatt and the sleeve 317 is slidably mounted thereon and prevented from rotating by a key 38. Links or arms 39 are secured to the sleeves and are. provided with weights or balls 40. v v

The sleeve 3T is connected to the slidable member 2G byan arm Ll1. As shown (see Figuren), the. slidable member is provided with a slot 42 'for the reception ot a bolt or pin 4?. carried bythe arm 41.

The operation ot the device is as t'ollows:

The arm 16 being slidably mounted on the depending' portion `ot the bracket l() is normally maintained in its lowered position with the contact 2O and the cam 22 in cngagement by spring 2f-LL, secured to the arm, at 25. Upon each revolution otl the sh att 2-37 the cam moves the slidable member QG to the left, in Figure 1 of the dri'iwing's. and s\.vin{;s the pivoted lever 15 on its pivot, raising; the arm 16 against the tension ot spring` Zet and separating the contact 2t) vfrom the cam. ln normal operation of the engine. the circuit is intermittently opened and closed ,in this manner. permitting the spark plug" 3 to be actuated in the usual manner.

lVhen the speed ot' the engine exceeds iv predetermined limit. and the balls or weights L,mare moved outwardly by centrifugal torce the sleeve 37 is moved toward the sleeve 3o ot the engine decreases and the slidable sleeve 37 assumes its normal position. The slot inthe slidable member Q6 is provided to permit normal operation of the timer without affecting the governor. Villien the slidable member is'actuated by the cam in normal operation. the pin 43 rides troni one. end ot y the slot to the other. without changing the position ol the connecting' member At1.

It is to be understood that the term ot mv invention herewith shown and described to bevtaken a preferred example o'tfvtlie.

same, and that various chantres inl the shape, size. and 'arrangement ot parts may be resorted to without departing "trom the spirit of the invention or the scope 'ot the snbjoined claims.
